Double-face usable duster and the method for making the cleaning cloth thereof

ABSTRACT

A double-face usable duster and the method for making the cleaning cloth thereof for cleaning dust off various articles comprises a first surface cleaning layer and a second surface cleaning layer and a central layer, each of the surface cleaning layers being formed by two layers of non-woven fabric through a hot-melt process. The central layer is an electrostatic precipitating portion sandwiched between the surface cleaning layers made of hot melt yarns. The three layers are combined to form the cleaning cloth of a double-face usable duster. Each of the surface cleaning layers is further provided with a plurality of sleeves for retaining a handle.

FIELD OF THE INVENTION

The present invention relates to dusters and methods for making the cloths thereof, more particularly to a double-face usable duster and the method for making the cleaning cloth thereof. The double-face usable duster thereby made has a central portion for cleaning irregular surfaces, and the inner layer and the outer layer can be swapped to extend the durability of the double-face usable duster.

BACKGROUND OF THE INVENTION

The dusters of the prior art are mainly feather dusters suitable for cleaning surfaces of large areas and less efficient for cleaning irregular surfaces. To clean irregular surfaces, a cleaning cloth is held by a hand and applied to a surface. The hand holding the cloth is easy to get stained, or the hand will wear a glove, which is inconvenient to a user in either case. Therefore, it is desirable to invent a duster for generally cleaning and cleaning irregular surfaces.

SUMMARY OF THE INVENTION

The primary objective of the present invention is to provide a double-face usable duster and the method for making the cleaning cloth thereof for cleaning dust off various articles. The double-face usable duster comprises a plurality of surface cleaning layers each made of two non-woven fabrics through a hot-melt process, during which process sleeves for retaining a handle arm are formed on each of the surface cleaning layers. Each of the sleeves has a closed end for preventing inserting the handle at a wrong end. Between the surface cleaning layers, there situates a central, electrostatic precipitating layer. The central layer is made of hot melt nodal yarns provided with nodes. The hot melt nodal yarns are a fabric interlaced by coarse and fine fibers capable of being hot-melted, whereby the fibers will not entangled. The central layer, the first surface cleaning layer and the second surface cleaning layer are bound together by hot melting.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

The various objects and advantages of the present invention will be more readily understood from the following detailed description when read in conjunction with the appended drawings.

Referring to FIGS. 2, 3, 4 and 5, a double-face usable duster according to the present invention comprises a first surface cleaning layer 1, a second surface cleaning layer 9, a central layer 8, and a handle 18. A plurality of sleeves 4, 12 are respectively formed on the outer surfaces of the first surface cleaning layer 1 and the second surface cleaning layer 9 when they are made. A plurality of elongated weld lines 5, 13 are respectively formed transverse to a selected longitudinal axis of the first surface cleaning layer 1 and the second surface cleaning layer 9.

The first surface cleaning layer 1 is combined by two layers of non-woven fabric through a hot melt process. The first layer of non-woven fabric is a needle-punched non-woven fabric with embossed mesh 2, and the second layer of non-woven fabric is a smooth hot melt non-woven fabric 3. Each of the sleeves 4 has a wider opening and a closed narrow tail section 6, taking the form of an elongated trapezoid. Thereby, a handle arm can be inserted and secured therein, and the closed narrow tail section 6 can prevent inserting a handle arm at a wrong end. Further, the outer portions of the cleaning cloth made of the first surface cleaning layer 1 and the second surface cleaning layer 9 are cut to form a multitude of transverse strips 7 for providing a more effective cleaning effect.

The central layer 8 is an electrostatic precipitating portion sandwiched by the first surface cleaning layer 1 and the second surface cleaning layer 9. The central layer 8 is made of hot melt nodal yarns with a node density of 50 per inch. The hot melt nodal yarns are a fabric interlaced by coarse and fine fibers capable of being hot-melted, whereby the fibers will not entangled. The central layer 8, the first surface cleaning layer 1 and the second surface cleaning layer 9 are bound together by hot melting.

The second surface cleaning layer 9 is combined by two layers of non-woven fabric through a hot melt process. The first layer of non-woven fabric is a needle-punched non-woven fabric with embossed mesh 10, and the second layer of non-woven fabric is a smooth hot melt non-woven fabric 11. Each of the sleeves 12 has a wider opening and a closed narrow tail section 14, taking the form of an elongated trapezoid. Thereby, a handle arm can be inserted and secured therein, and the closed narrow tail section 14 can prevent inserting a handle arm at a wrong end. Further, a multitude of transverse embossments 15 are formed on the outer surface of the second surface cleaning layer 9 for providing a more effective cleaning effect.

A double-face usable duster 16 thereby formed is further provided with two elongated openings 17 respectively along the respective longitudinal axes ending at the elongated weld lines 5, 13. The elongated openings 17 have the effect of expanding the cleaning surface of the double-face usable duster 16.

Referring to FIG. 7, a handle 18 is inserted into the sleeves 4 on the first surface cleaning layer 1, forming a double-face usable duster 16. The double-face usable duster 16 is capable of cleaning a variety of articles, and, especially, the elongated opening 17 is suitable for cleaning irregular surfaces. When the cleaning cloth is dirty, the handle 18 is pulled out and the cloth is flipped so that the second surface cleaning layer 9 becomes the outer layer. The handle 18 is reinserted into the sleeves 12 on the second surface cleaning layer 9, as shown in FIG. 6.

Referring to FIGS. 1, 2, 3 and 4, the double-face usable duster and the method for making the cleaning cloth thereof are illustrated.

The method of making the cloth of the double-face usable duster is illustrated in FIG. 1, which comprises the steps of piling up a needle-punched non-woven fabric with embossed mesh 2 and a smooth hot melt non-woven fabric 3 to form a first surface cleaning layer 1, being cut to form a multitude of transverse strips 7, yarn setting and five-layer combining processing.

The central layer 8 is formed by the steps of processing coarse fibers capable of being hot-melted into hot melt nodal yarns, yarn setting and five-layer combining processing.

The second surface cleaning layer 9 is formed by the steps of piling up a needle-punched non-woven fabric with embossed mesh 10 and a smooth hot melt non-woven fabric 11, cutting the second surface cleaning layer 9 to form a multitude of transverse strips 15, yarn setting and five-layer combining processing.

The first surface cleaning layer 1, the central layer 8, and the second surface cleaning layer 9 are then piled up and undergo the steps of yarn setting, five-layer combining processing, and five-layer hot stamping.

The first surface cleaning layer 1 and the second surface cleaning layer 9 of the cleaning cloth are cut to form respective elongated openings 17 extended along the longitudinal axis and ended at the weld lines 5, 13. The cloth is then folded about its longitudinal axis to form the final configuration of the double-face usable duster.

The handle 18 is inserted into the sleeves 4 on the first surface cleaning layer 1 to form the double-face usable duster 16, as shown in FIG. 7, which can cleaning a plurality of articles. The elongated opening 17 of the double-face usable duster 16 is especially suitable for cleaning irregular surface of some articles. When the cleaning cloth is dirty, the handle 18 is pulled out and the cloth is flipped so that the second surface cleaning layer 9 becomes the outer layer. The handle 18 is reinserted into the sleeves 12 on the second surface cleaning layer 9, as shown in FIG. 6.
